Summary

The State of Food Security and Nutrition in the World 2026 (SOFI 2026) is the annual United Nations flagship report on global food security and nutrition, jointly produced by FAO, IFAD, UNICEF, WFP and WHO. Each edition tracks progress towards SDG 2 (Zero Hunger) and carries a thematic deep-dive; the 2026 edition’s theme is the high cost of a healthy diet, built around the Cost of a Healthy Diet (CoHD) indicator, the minimum daily budget needed to buy the least-cost locally available foods that make up a healthy diet. Its headline is that food access, not just food availability, is now the binding constraint: an estimated 2.69 billion people (32.7 percent of the world) could not afford a healthy diet in 2025, and the global mean CoHD has climbed to 4.28 PPP dollars a day. For the thesis it is the authoritative, current backdrop that reframes food self-sufficiency as an affordability and access problem, quantifies the structural cost drivers (post-farmgate logistics, transport, electricity) that a remote community’s food is most exposed to, and explicitly places non-market, own-production food access outside the CoHD, which is precisely the gap community-scale food self-sufficiency fills.

Key thesis insights

  • The binding problem is affordability, not availability, and it is worsening in real cost. An estimated 2.69 billion people (32.7 percent of the world population) could not afford a healthy diet in 2025, down from a peak of 3.13 billion in 2020 and 2.97 billion (37.4 percent) in 2021, while the global mean CoHD rose to 4.28 PPP dollars in 2025 from 3.44 in 2021 and 2.94 in 2017; the share unable to afford a healthy diet (PUA) is highest in Africa at 66.6 percent, more than double Asia (28.9 percent) and Latin America and the Caribbean (25.7 percent) (Executive Summary, p. xvi). This quantifies the cost barrier that makes economic access to nutritious food, not mere production volume, the salient problem the thesis’s food-self-sufficiency argument responds to. OT_199
  • Own production sits explicitly outside the market cost floor, which is the gap self-sufficiency fills. The CoHD is a market cost benchmark: FAO states it “does not measure, nor is it meant to reflect… non-market food access, such as intra-household food production,” and the report “relies on market valuations rather than a true-cost accounting framework” (Executive Summary, pp. xviii–xix). The CoHD therefore establishes a cost floor that household- and community-level food production bypasses entirely, giving the thesis an authoritative FAO framing for why local, non-market food self-sufficiency is a direct hedge against the affordability barrier the report documents. OT_199
  • The cost drivers are post-farmgate logistics, transport, electricity and connectivity, exactly the remote-community premium. Post-farmgate activities account for 70 to 75 percent of what consumers pay, with up to 40 percent of value-chain costs accumulating in midstream processing, logistics and wholesale; and a lower CoHD is associated with “higher agricultural productivity and crop yields, sustained public investment in research and development, efficient logistics and transport (including better road quality), mobile connectivity, effective trade integration, and lower electricity and labour costs” (Core Messages, p. xiii). These are precisely the factors that inflate food prices for remote and off-grid communities, so the report substantiates the thesis’s case that local production and the enabling infrastructure (energy, connectivity) offset a structural remoteness/transport premium. OT_199
  • Cost concentrates in the perishable, nutrient-dense groups a self-sufficient community must produce locally. The Healthy Diet Basket comprises 11 food items across six food groups delivering 2 330 kcal/day, with starchy staples the largest energy share (1 160 kcal) and animal source foods, legumes/nuts/seeds and oils/fats at 300 kcal each, fruits 160 kcal and vegetables 110 kcal; yet animal source foods, fruits and vegetables contribute “nearly 70 percent of the total cost,” while starchy staples contribute “only one-sixth of the total cost despite providing half the calories” (Executive Summary, pp. xviii–xix). This maps directly onto the project’s food-domain work: the expensive, perishable, nutrient-dense groups (animal source foods, fruit, vegetables) are exactly the ones local community production most needs to close, and where the market cost barrier bites hardest.

  • Closing the food-access gap needs a socio-technical enabling environment, not technology alone. Against a backdrop of 645 million people facing hunger in 2025 (7.8 percent prevalence of undernourishment) and 2.1 billion (25.8 percent) moderately or severely food insecure, FAO stresses that translating agricultural-productivity and R&D gains into lower diet costs “requires enabling systems, including seed delivery, water management, land tenure, finance and extension, that support technology adoption” (Executive Summary, p. xvi; Core Messages, p. xiii). This is an authoritative endorsement of the thesis’s core claim that technology only delivers when paired with governance, tenure, finance and capability, the socio-technical enabling conditions, rather than as a standalone fix.

Research targets

None opened and none resolved. This is a proactively-retrieved authoritative backdrop source for the thesis’s food-security and food-self-sufficiency framing; it corroborates and updates the affordability/access argument rather than filling a specific backlog gap. If a national CoHD figure for New Zealand is needed later, the report notes UN agencies are supporting national CoHD estimates from national retail price data, a possible future retrieval.

  • Reading scope. Read verbatim: In Brief / Core Messages (pp. xiii–xiv) and Executive Summary (pp. xv–xxi). The report body (Chapters 1–4, ~249 pp total) was not read; every figure quoted above sits in those front-matter sections.
  • Scope and caveats. Global assessment reported in PPP dollars; no NZ-specific data and nothing that feeds an NI calculation cell. The CoHD’s underlying food-price data come from the World Bank International Comparison Program (ICP), with a 2021 reference year for food-group cost shares and inflation-adjusted 2025 estimates; FAO flags ICP limitations (item coverage, one national-average price per item, temporal coverage). data_quality: high (authoritative UN flagship, single-source; not verified, which the project reserves for figures corroborated by an independent source).
  • Companion to the sibling FAO sources (SOLAW 2025 on land and water, SOFA 2025, the disasters-and-agriculture report): together they form the global food-system backdrop for the thesis. SOFI 2026 is the affordability/access piece of that backdrop.
